devs Posted February 13, 2016 Share Posted February 13, 2016 The way I read Richard's/W4S's posts is that the RUR needs the 5V present for handshake purposes only. It's current draw is not specified. The Intona is perfectly capable to provide the 5V voltage up to a certain current draw. Up to around 300mA if I'm not mistaken, after that the voltage gradually drops to 4.5V. This is because it itself requires and uses USB bus power. This assuming there's 500mA to start with from the USB port.
